Yes, that should be OK.

Likely the reason you needed VTSWITCH=Y in the first
place has to do with it catching the SIGUSR1 signal. There's
nothing else in the vtswitch code doing anything funny,
is there?

It would be interesting to learn why the vtswitch code is
required for your sleep mode. Otherwise, you know how
programs are, one Tuesday the stars may align without
your permission... I think you're fix will work for the
long term, however.
